  • Retractable Y-shaped foils, adjustable in three dimensions

    Inspired by the appendages of the America's Cup foiling monohulls, these Y-shaped foils have a wingspan of over 5 metres. They are designed to generate powerful lift, increase power and offer a wide range of adjustments to optimise flight at every point of sail and in all conditions. Beyond their impressive size, these foils feature many unique innovations.

    Revolutionary U-shaped rudders

    These are probably the most visually striking innovations on the new Maxi Edmond de Rothschild. To fly high above rough seas while maintaining control, the team wanted very long rudders that would remain in contact with the water. The challenge is that longer rudders tend to flex under load, severely affecting steering and the efficiency of their lifting surfaces. A new geometry was needed to give these appendages maximum stiffness, resist cavitation and ultimately improve control of the boat and make better use of its power. The result is a set of U-shaped rudders over 4 metres long, a metre longer than those on Gitana 17. Their shape, reminiscent of a tripod or an inverted π, is only the visible part of what makes them so distinctive.

    A daggerboard optimised to stabilise the boat and limit cavitation

    With its wide span, the daggerboard resembles an aircraft tail assembly, with two adjustable flaps: one on the vertical section and the other on the horizontal section, the distinctive “manta-ray wing”. On Gitana 18, the innovation is to position this wing behind the vertical part of the appendage, rather than directly beneath it, to minimise flow disturbance and cavitation.

    Rig: adjustable spreaders to control mainsail power while sailing

    Gitana 18’s mast is 1.50 metres taller than its predecessor’s. The boom is also shorter, creating a more slender sail plan. The major innovation is a set of spreaders that can be adjusted while sailing to bend the mast fore and aft. Actuated by hydraulic rams, these spreaders can pivot through 35 degrees to adjust the bend in the middle of the mast. This unprecedented system allows the sailor to control mainsail power: adding depth in light winds to take off sooner, or flattening the sail to reduce power at high speed or in strong winds. Adjusting the depth, and therefore the power, of the mainsail can also save a solo sailor time and energy by reducing the need for risky manoeuvres or headsail changes.

    Central hull:
    an integrated, structural coachroof

    The naval architects and Gitana design team wanted an exceptionally stiff, structurally robust platform. This applies both to the floats, which must withstand heavy loads from the foils and rudders, and to the central hull, which is subject to torsion. The enclosed coachroof is integrated into the hull and contributes to its structural strength. Inside, the cockpit brings all sail-handling controls together, with ergonomics shaped by many hours of design and development. The coachroof also stands out for the number and size of its windows. This configuration meets the visibility requirements of the Ultim class rules and gives sailors the best possible view to keep a visual watch.

    The Maxi Edmond de Rothschild leading at Robben Island.

    And that makes two! At 19:16 UTC, this Wednesday 20 November, the Maxi Edmond de Rothschild was first around Robben Island, the second course mark in the Brest Atlantiques. In this way, Franck Cammas and Charles Caudrelier consolidate their lead after 15 days 9 hours and 16 minutes of racing. At the 19:00 UTC position report, the duo on Gitana Team…

    And that makes two! At 19:16 UTC, this Wednesday 20 November, the Maxi Edmond de Rothschild was first around Robben Island, the second course mark in the Brest Atlantiques. In this way, Franck Cammas and Charles Caudrelier consolidate their lead after 15 days 9 hours and 16 minutes of racing. At the 19:00 UTC position report, the duo on Gitana Team had a 165.6-mile lead over Macif and 189.9 miles over Actual Leader, respectively second and third. Gitana 17 took 6 days and 7 hours to cover the 3,300 miles of what proved to be a testing passage across the South Atlantic between Rio de Janeiro and Cape Town.
    A dark night on Robben Island

    The second and last official course mark of the Brest Atlantiques is Robben Island, in South Africa. This island, located around 7km to the North of Cape Town and dominated by Table Mountain, is an illustrious passage point. Indeed historically, Robben Island is known for having been the place where Nelson Mandela was imprisoned for over seventeen years.

    However, in contrast to Rio de Janeiro, which the Maxi Edmond de Rothschild passed on 14 November at 12:16 UTC, it was under the cover of darkness that Charles Caudrelier and Franck Cammas left the island in their wake. Despite this, Yann Riou, media man on the Maxi Edmond de Rothschild managed to fly his drone for a few minutes before sunset whilst the giant was powered up en route to Cape Town making over 40 knots! The result was some rare and fabulous images, which once again illustrate the reporter’s great talent.

    A testing passage across the South Atlantic

    Over the 3,300 miles separating Rio de Janeiro and Cape Town, the Brest Atlantiques fleet has not be spared by the weather conditions. Leading the way, the Maxi Edmond de Rothschild is no exception to this rule, quite the contrary in fact. Indeed, like her rivals, the latest Gitana had to hunker down during the first days of this passage across the South Atlantic as she rounded to the North of a powerful low pressure system. For over 48 hours, normal daily life aboard the giants was shaken about somewhat given how difficult the seas were with the men and of course with the machines! In the second part of the crossing, the maxi-trimaran with five arrows had to dive a long way South, beyond the forty-degree latitudes to round the abnormally low Saint Helena High. This detour was accompanied by a series of gybes along the ice exclusion zone put in place by Race Management, whilst behind them their pursuers were able to set a much more direct course towards Cape Town.

    However, in these demanding conditions, Franck Cammas and Charles Caudrelier posted a performance that was very much true to form, getting the very best out of their steed by setting a steady pace which their rivals could but follow. These same adversaries have been somewhat unfortunate in this second section of the course, as is the case for Sodebo Ultim, which collided with a UFO (Unidentified Floating Object) two days ago. Thomas Coville and Jean-Luc Nélias are lamenting the loss of their starboard rudder as well as part of the float following this incident. They’ll be carrying out a pit stop in Cape Town tomorrow morning to carry out further investigations. Team Macif has also just announced a pit stop over the coming hours…

    For the men on the Maxi Edmond de Rothschild, there’s no question of hanging around in these latitudes. Indeed, the weather forecasts are obliging them to hit the road for home as quickly as possible, before the Saint Helena High climbs back up to her usual position, namely not far off the island that it is named after. 

     

    Message from onboard by Yann Riou

    Bound for Cape Town, heading North!

    Since the start of the night, we’ve stopped weaving our way along the ice zone and we’ve set a course for Cape Town, which means northwards. It’s also the first time that we’ve been closing on Brest, with the exception of a few marginal tacks just to be entirely accurate. We’re leaving the forties, which weren’t especially ‘roaring’ this time. To be honest, the setting was quite similar to what you get offshore of Lorient during the same period… with the exception of a few albatross! These famous albatrosses! Talking of which… before we got to Gough Island, Franck said to me:
    “We’ll soon start seeing albatross”. Two hours later, at dusk, I spotted one! Now there’s a guy who’s familiar with this neck of the woods… I rush to get my camera. Too late, too late, too dark.
    Since then, I’ve been keeping watch. I’m lying in wait for the animal, camera in hand, ready to snap him. I have spotted one or two. But too late, too late, too dark. This morning, we’re officially out of the forties. Busy removing fleece layers, I glance out on deck. This time, he’s not too far away. However, my camera was charging down below, inside the central hull, where it’s too dark. By the time I’d tracked it down, naturally it was too late. I ended up removing my second fleece layer. We’re entering the ridge of high pressure. This evening we’re rounding Robben Island, passing in front of Cape Town and then heading homewards!
